一种sip网络系统中解决nat网络环境下正常呼叫的方法

Method for solving normal call under network address translation (NAT) network environment in session initiation protocol (SIP) network system

Abstract

The invention discloses a solving method of session initiation protocol (SIP) call in a network address translation (NAT) environment, which is low in network consumption. In the SIP network system, SIP users in private networks log in an SIP server in a public network through a router, so that terminals in different private networks can mutually communicate normally without occupation of the rated bandwidth of the SIP server under a circumstance of not changing or upgrading the current router. According to the technical solution, by the method disclosed by the invention, normal communication of the SIP terminal is achieved in the normal router NAT environment, and the market demand is met.
本发明提供一种较少网络消耗,在NAT环境下SIP呼叫的一种解决方法,所属SIP网络系统中,在私网内的SIP用户通过路由器注册到公网的SIP服务器,在不改变和升级当前路由器的情况下,实现在不同私网内的终端相互正常通话,而且不占用SIP服务器额带宽。从上述的技术方案可以看出,本发明可以在普通的路由器NAT环境下实现SIP终端的正常通话,满足了市场的需要。
